Christina Aguilera got the most romantic Valentine's Day present. Her boyfriend, film producer Matt Rutler, proposed and Xtina accepted. She was quick to show off the ring, too.

The 2013 American Music Awards were rife with amazing performances from Katy Perry, Ariana Grande, One Direction, Rihanna, Miley Cyrus, Justin Timberlake, Christina Aguilera, Pitbull featuring Kesha and more. And you can catch them all here!

Simplicity is key in the emotional video for the Christina Aguilera x A Great Big World duet 'Say Something.'

Christina Aguilera is being suuuuuuuper picky about her projects right now, and, well, she has earned that right. Singer-songwriter duo A Great Big World have found their way onto Xtina's radar with their moving single 'Say Something,' an achingly beautiful song that will be performed live by Xtina and the twosome on 'The Voice' tonight (Nov. 5).

We don't think we can say enough that Christina Aguilera has come a long way in gaining her svelte frame back, so here it is again: Christina Aguilera looks amazing. Last night (Sept. 18) she showed off her toned and trim body on 'The Tonight Show With Jay Leno' in a little black dress, and boy was it black and little.

Last time we got a good look at Christina Aguilera in July, she appeared pretty and fit. But her slimmed-down style on last night's (Sept. 18) 'Tonight Show With Jay Leno' was simply stunning!

Whoa! Christina Aguilera is white hot on the cover of the October issue of Maxim, wearing little more than a black bra that can barely contain her, a crisp white men's shirt and a pout.

Christina Aguilera emerged from a bit of a hiatus from 'The Voice' -- she sat out Season 4 -- looking her very best while promoting the upcoming fifth season in a blush micro mini by Alaia. She shed some excess baggage, ditched the ubiquitous crimson lips and wowed us. It inspired us to take a look back at her recent style.

What a difference a season off makes. Christina Aguilera, who took a hiatus from 'The Voice,' will be back this fall. And while she didn't tour in support of her album 'Lotus' (which tanked), she did use her time wisely: She got herself in incredible shape, looking better than she has in years.

Pitbull and Christina Aguilera had a true "A-Ha moment" at the 2013 Billboard Music Awards with 'Feel This Moment.'

Christina Aguilera took a break from 'The Voice' season 4 to focus on other things, though promoting 'Lotus' wasn't one of them. In any case, the diva will be back in her big red chair for season 5 of the NBC hit this fall -- for a price.

Seriously, you guys. You are not going to want to miss the 2013 Billboard Music Awards. Trust us. It has been announced that Pitbull, Christina Aguilera and Macklemore & Ryan Lewis have been added to the performance bill. This should be one wild party!
